Course description and aims

This course is a comprehensive introduction to concept, models and technologies of database systems that are now regarded as the most important infrastructure of information systems.
At first, it gives the relational database models with the relational algebra, relational calculus, and normal forms. It then explains the conceptual modeling, query languages including SQL, and the important concept of transactions including the concurrency control and recovery. Technologies for storing data, indexing, and processing queries are also treated. It introduces recent trends of databases, such as Object Oriented, XML and RDF databases.

Student learning outcomes

By the end of this course, students will be able to
1) Understand the basic concept and models of databases
2) Design databases in normal form satisfying requirements
3) Write appropriate queries for databases
4) Handle concurrency control and recovery of transactions
5) Use techniques for storing data, indexing, and processing queirs
6) Have knowledge about recent trends of databases
